Total
QSO points on all bands X (multiplied by) the sum of multipliers on all bands.

X.General Rules

a) All transmitters and receivers must be
within a single 500-meter radius circle.

All antennas used by an entrant must be
physically connected to the transmitters by wires (feeders).

b) Single Operator participants may change
bands and modes without restrictions. Only one signal can be transmitted at any
given time.

c)MOST stations are limited by 10 minutes rule. Only one transmitted
signal on one band permitted during any 10-minute period (run transmitter).
Exception: One and only one other transmitted signal (multiplier transmitter)
may be used during any 10-minute period, if and only if it is on a different
band than the run transmitter and the station worked is a new multiplier. The
run and multiplier transmitters are governed by independent 10-minute rules.
Ten-minute periods begin with the first QSO on a band. The log must indicate
which transmitter (run or multiplier) made each QSO. The multiplier transmitter
may not call CQ or solicit contacts.

d)
The use of the DX-Cluster system (packet cluster, web cluster) is allowed, for
all categories of participants.

e) Forbidden and penalized with
disqualification:

- Self-spotting (posting your own call on
the cluster)

- Fake spotting (posting on the cluster
using fake call signs)

- Spotting of your call sign by other
stations as a result of a prearranged solicitation (by phone, fax, internet,
mail, etc.)

- Remote receivers outside the station
location.

f) The use of public Skimmer and/or Reverse
Beacon Networkis allowed for all
categories. The use of a local skimmer is allowed only if its hardware is
located in the same location with the entrant station (within the 500m radius
circle).

g) Remote operation is permitted if the
physical location of all transmitters, receivers, and antennas are at one station
location. A remotely operated station must obey all station license, operator
license, and category limitations.

h) Post-contest correcting of call signs by
using any database, recordings or confirming QSO's is not allowed.

XI.Instructions for Preparation of Logs

All logs should be submitted in Cabrillo
format (even check logs).

Other recommendations:

All times must be submitted in UTC (time differences of maximum +/-5
minutes are allowed between correspondents)

The complete controls exchanged during the QSO must be reported

The name of the file must contain the call sign of the participant. The
file will have the extension .cbr or .log

The header of the log must contain the category, name and complete
address, the association or club name, as well as other specific information
(age, if under 16, XYL/YL, etc.). Additionally, if the participant wants to be
framed in a specific band, although he worked in multiple bands, this will be
specified in the header.

Paper based logs are also accepted. These will be converted in .cbr
format by the referees or other volunteers who are not competing for the first
positions. The errors which might appear while introducing the data shall not
be disputed after publishing the scores.

It is not necessary to provide the points or the final score. This will
be done by the verification software.

For the electronic submission, in the “Subject” line of your email
please include your call sign. Participants will receive a confirmation email
in maximum 72 hours after the log has been received.

XII.Trophies and Awards

Participants on 1st, 2nd and 3rd places
from each category will receive awards.

The 1st place on each category (according
to chapter V) will receive a plaque.

A separate classification will be issued for each country. Depending on
the number of participants from each country, awards will be offered:

1-9 participants: 1st place

10-19 participants: also 2nd place

20-29 participants: also 3rd place, etc.

A Top 10 by continent classification will be issued. The winner of each
continent will be awarded with a plaque.

Plaques will be offered to the operator with age under 16 and to the
YL/XYL operators with the highest score (only if they submitted the contest log
and if the requested information is specified in the log).

All the stations that submitted the log
will receive by e-mail a Participation Certificate in electronic format (PDF),
the final scores and any news regarding YO DX HF Contest.
